“| eee ILLUSTRATIONS “are “descriptive: ofmvariens 
styles of Sheet Metal Window Frame and Sash, designed for 
buildings where fire-proof construction is desired. 

In new buildings the frames are designed to be built in the 
walls ; in old buildings where they replace wooden frames and 
sash, they are anchored to wall with iron stays. 

The sash can be sliding, to work with chain and weights, 
or they can be pivoted or hinged. 

The frame and sash are made of galvanized iron, all joints 
being thoroughly riveted and locked and then soldered, insuring 
strong, neat, flush joints that can not be separated by fire, and 
presents a smooth surface for finishing. 

The Simplicity in Construction permits of quick access to the 
Weight Boxes, the sash, chains and weights being more easily 
adjusted than in ordinary wood frames. 

The Sash are glazed with Wire Glass, % inch thick, thereby 
dispensing with the unsightly tin covered shutters. If desired 
for Offices, Stores, etc., polished plate wired glass can be sup- 
plied, which admits a clear, unobstructed light. | 

The entire construction is Firm, Durable, Fire-Proof and 
Weather-Proof, the sash fitting snugly in the grooves and being 
firmly locked when closed. Any size or shape of window can 


be produced without limit to architectural effect.

Wire-Glass. 


Inspectors and surveyors of fire insurance companies and 
all well-informed underwriters, consider wire-glass a most effec- 
tive and reliable fire-stop when it is glazed or set in non-com- 
bustible sashes or frames. It may be placed in fire-wall 
partitions, in elevator shafts, or it can be safely used in the 
exterior openings to resist either external exposure or to confine 
the fire to the buildings glazed with it. 

No one, familiar with exposure hazards, has foreseen any 
condition in which the wire-glass, if properly put up, might not 
on inspection, prove entirely satisfactory as a substitute for 
standard shutters. All believe they would prove better fire- 
stops than the iron shutters called for by the rules of the 
building departments in large cities. The tests to which this 
style of glass has been subjected in many parts of the country, 
show it to have remarkable and surprising qualities as a fire- 
stop, and if the standard of workmanship on the frames and 
sash are kept up, there is no reason why it should not supplant 
the cumbersome fire doors and shutters. 

Wire-glass is made in hammered, ribbed and polished plate. 
Polished plate wired can be used in office and store windows, 


through which objects can be seen without distortion.

WI RE-=G LASS—cContinued , 


Reasons why ,Wire-Glass Metallic Frames and 
Sash are¥supplanting Fire Shutters. 


Because they are a positive resistant to the spread of fire, 
and do not depend on circumstances to make them effective ; 
they protect all the time. 

Shutters have to be opened for light and closed for protec- 
tion, requiring the expenditure of considerable labor. 

Wire-glass windows need no such labor expended on them, 
they protect all the time. 


Wire-glass windows make as resistant a fire-wall, as though 
it were built solid. 


Wire-glass windows are practically burglar proof, as the 


glass could not be broken without considerable noise.

A Severe Test of the ‘‘Rasner”’ 
Sash and Frame. 


this city. 

We had a brick building built 6 feet square and 8 feet high, with a 
heavy corrugated iron roof on same, iron grate bars were placed at the bottom 
of the house, and openings left near the bottom for draft. The window frame 
and sash was placed in the front of the building, wood saturated with oil was 
piled up high on the outside against the frame and sash, and a continuous hot 
fire was kept up against this frame and sash for one hour without getting in- 
side the building or doing any damage whatever ; after which a stream from a 
fire hose was kept playing on it until cooled off. This test was made in the 
presence of the Board of Fire Underwriters, Chief Inspector McDevitt, Chief 
Engineer Baxter of the Fire Department, representatives from Fire Insurance 
Companies and a number of property owners, and gave great satisfaction to 
those present. 

The above test was made from the outside, where the most danger lies 
with high buildings, from outside conflagrations in close proximity, or narrow 
streets. A few days after another test was made of the same frame from the 
inside, in the presence of a number of builders and business men, and the 
frame and sash went through the fiery ordeal and came out intact. 

A test was made at Pittsburgh on January 18th, 1899, in the presence 
of the Board of Fire Underwriters, Architects, and Officials of the Bureau of 
Fire. A brick building was built 6 feet wide, 8 feet long and 11 feet high, in 
imitation of corner of top floor of large building; into this was fitted the Ras- 
ner Patent Hollow Galvanized Steel Window Frame and Sash, Glazed with 
Wire Glass. Two anda half feet from this window a frame structure was 
built of same size, filled with combustible material saturated with oil; it 
burned with great fierceness, the firemen at times threw water on the win- 
dow which was almost at a white heat; the fire was allowed to burn two or 
three times, and new material was thrown in, so that the Patent Window was 
cooled and heated again in quick succession. The window was not warped or 
burned, and after the fire, could be raised and lowered as easily as before. 
The test was made to prove that windows in buildings fitted with these hollow 
sheet steel frames and sash will not burn or break from the heat of an ad- 
joining burning building, thus preventing the fire spreading.

the supervision of the secretary, assisted by inspector Wm. McDevitt. 


November 17, 1898, Rasner Frame. 


A small brick building having openings top and bottom for draught was 
constructed for this purpose, having a window on one side and iron door on 
the opposite side, roof being of corrugated iron. The window contained a 
Rasner metal window frame and double hung sash constructed by J. S. Thorn 
Co., and described as follows: The frame was formed of No. 24 galvanized 
sheet metal jamb forming weight boxes in either jamb of frame with parting 
strips of sheet metal on interior and double thick sheet metal flanges on face 
of pulley stylings upon which the respective sashes slid ; the sill being formed 
of similar metal on wooden quirked and beveled sill core. The head being 
also formed on wooden core entirely covered with said sheet metal, the heads 
and sills united to the jamb boxes by means of interior rivetings and retaining 
flanges, proper stop beads being worked into soffit of frame to receive and 
retain sashes in place. ‘The sashes being of hollow sheet metal section, with 
3g-inch by !%-inch re-entrant grooves for glass in all stylings and rails, and 
similiar back grooves on all sashes next to pulley styles to receive the afore- 
said flanges on pulley styles of frame; the glass being introduced through 
open slot 34-inch wide in top rail of all sashes, which slot was closed by 
means of cap of galvanized iron bolted in place. ‘The angles of sashes being 
lapped and riveted independently on both faces, each sash being glazed with 
one pane 14-inch wire glass measuring 2 feet 6 inches by 1 foot ro inches. 

This window was subjected for one hour to heat from a fire of wood 
moistened with kerosene oil built outside of window up against the same. 
The pyrometer indicated at various times a temperature of about 1400° to 
1600° between the fire and the window. At the end of the hour a stream of 
water was thrown upon the frame and sash (about fifteen pounds pressure) 
and then the fire was extinguished. Examination of the window after the test 
showed that both the sash and the frame as well as the glass were practically 
uninjured. 

In order to ascertain the amount of heat which would radiate from the 
reverse side of the glass so as to determine how close to a wire glass window 
merchandise could be allowed, strips of bagging were hung on the inside of 
the building, one 12 inches from the glass and another 36 inches from the 
glass. Thirteen minutes after the fire had been started the bagging nearest 
the glass ignited and dropped to the ground; ten minutes later, or twenty- 
three minutes after the fire was started the bagging farthest from the window 
also ignited and dropped to the ground.

In store and office buildings, where it is desirable to see through, frames with three sashes 
can be used, two of which are provided with wire-glass, and one with ordinary transparent glass, 
the wire-glass sash being intended to screen or close the window opening. The upper wire-glass 
sash is maintained in its position by a fusible catch, whereby the same automatically lowers over 
the transparent sash in case of fire.
